Wallace has built a machine to make Christmas cards, with a camera hooked up to take the pictures for them. He has set up a crudely built snowy landscape in the living room, and Gromit - dressed in a bird costume - is reluctantly posing for the pictures. Wallace is pleased with the results, then hoists the backdrop away and walks off, not noticing the picturesque winter scene outside the window. The birds perched out here wave to Gromit, and one blows a party noisemaker at him when Wallace calls out for him to lick the stamps.

To speed up Gromit's chores of sweeping up, Wallace activates the 525 Crackervac, a vacuum cleaner with sharp metal teeth that can suck up cracker crumbs at high speed. When it starts trying to snatch a packet of Wallace's crackers, he yanks the box away and throws it to Gromit, who eventually lassos the machine and rides it like a rodeo bull. Gromit ties a knot in its suction hose, causing the rear end to burst and shower dirt all over both Wallace and the area of the room around him. He woozily asks Gromit to get the dustpan and brush he had been using at the start.

While trying to repair the Autochef, Wallace tries a new replacement contraption, the coin-operated Turbo Diner. After he inserts a coin into the wall panel, he and Gromit sit at the table and the device clamps down their wrists and ankles. A powerful vacuum sucks all the debris off the table, after which another mechanism sets it, delivers a fully cooked meal, and lights the candles (with Gromit avoiding the flame jet it uses for this last). Once the table is ready, though, the Turbo Diner's meter runs out and the two are left clamped to their chairs, unable to reach the coin slot or controls. After the candles burn out leaving the pair in darkness, Wallace says, "Don't worry, I've got a great idea", in homage to The Italian Job.

To activate the TV set without leaving his chair, Wallace launches a tennis ball into a hole in the wall. It triggers a mechanism that extends the TV across the room on a telescoping shaft, so that Wallace can reach the on/off and channel buttons. When he accidentally tunes into the wrong program, he finds that he has no more balls available; Gromit hands him the TV remote, but he throws it into the hole instead of using it normally. The remote jams the mechanism, causing the TV to shoot across the room and pin Wallace to the wall.

To speed up the task of bringing cheese home from the shop, Wallace deploys a remote-controlled trolley equipped with a camera and accessories to retrieve/carry items. Though it successfully picks up the largest wheel of Edam in the shop Wallace frequently patronises, the weight causes one wheel to fall off. Gromit guides it to grab a loaf of French bread, which it uses as a crutch to limp home. The other wheel comes off at the front door, stopping the trolley and, in the process, dumping the Edam in the garden. Wallace sends Shaun the Sheep to bring it in, but Shaun begins eating the cheese instead. Wallace keeps calling Gromit, who is still in the basement, to stop Shaun, but Gromit ignores him while Shaun happily munches away on the cheese. This short contains numerous references to NASA, especially the Apollo 13 mission.

On a stormy night, Wallace nervously ventures into the kitchen to get his tea, not noticing a figure that hides in the shadows. He sits down to eat a cracker, only for it to be snatched out of his hand and reappear in a corner of the room. The figure turns out to be Gromit, who advances on him threateningly with a rolling pin, but Wallace activates the Bully-Proof Vest strapped to his chest. A spring-loaded boxing glove pops out, knocking Gromit across the room and through a door, and Wallace declares the invention a success. However, he trips on the rolling pin and falls, triggering the vest so that it launches him upward with enough force to embed him in the ceiling.

To speed up his cooking, Wallace activates the Autochef, a robot chef with a tea nozzle, a frying pan and a temperature gauge. He has it cook scrambled eggs, but they end up on Gromit's head instead of a plate. Next Wallace tries to fry eggs, but the Autochef throws them onto Wallace's face, blinding him. As it goes haywire and starts to squirt hot tea around the room, Gromit blocks the nozzle with a banana. The pressure buildup causes the Autochef's head to explode (after comically saying "knickers") and destroy the dining room, and Wallace decides to have a continental breakfast the next day.

Wallace is unable to sleep after eating too much cheese, so he activates his Snoozatron to remedy the problem. The device wakes up Gromit, who puts on a sheep costume and heads downstairs; meanwhile, robotic arms fluff Wallace's mattress and pillow, place a hot water bottle on his chest, and give him a teddy bear as a record of lullaby music starts to play. After Gromit reaches the dining room, a huge spring built into the floor repeatedly bounces him upward, through a trap door in the ceiling, and into Wallace's bedroom. Wallace literally counts sheep and soon falls asleep, but the mechanism continues to bounce Gromit up and down as he gets bored and starts reading the newspaper.

Wallace and Gromit head to the local football field for a bit of practice, with Wallace shooting and Gromit playing goalie. Frustrated at the ease with which Gromit blocks every shot, Wallace activates his Preston North End Soccamatic, a machine that kicks dozens of balls toward the goal. Gromit ducks to avoid the barrage, but when Wallace stops to load in more balls, he dons a vest and gloves that inflate to completely block the goal. Wallace suggests that they switch to tennis; after the credits, he serves a ball that bounces off Gromit's vest, then calls out, "15-love!"

For the annual Grand Snowman Competition, Gromit is building a snowman that depicts Wallace as Rodin's "The Thinker," but is interrupted by the arrival of Wallace with his new Snowmanotron machine. It builds a crude snowman and crushes the body of Gromit's creation, whose head falls off in his paws. An annoyed Gromit goes back into the house, slamming the door hard enough to dump a load of snow off the roof and onto Wallace so that it covers him completely. Mistaking Wallace for a better-looking snowman, Gromit adds a carrot nose and eyes. He wins the competition, but Wallace catches a cold and has to thaw out at home.

A Matter of Loaf and Death is a murder mystery, with Wallace and Gromit starting a new bakery business. With an unknown assailant murdering bakers, Gromit tries to solve the case before Wallace ends up a victim himself.
